Indian fertilizer industry is growing day by day. Enumerate the environmental concerns related with the growth of this sector in India.
The fertilizer industry has been classified under the ï¿½red categoryï¿½ of polluting sectors by the Central Pollution Control Board .It causes following environmental concerns:
- The discharge of untreated or partially treated industrial waste water is the main source of pollution of ground water
- According to the BIS,ï¿½the maximum permissible limit of ammonia in drinking water is 0.5 ppm. However, about 83 per cent groundwater samples collected had an ammonical nitrogen content of 0.51ï¿½93.5 ppm. This upper limit of which is 187 times the permissible limit set by BIS
- Some plants are diluting their wastewater with freshwater to meet pollution control norms
- Inefficient air pollution control devices or improper fuel combustion within the systems have led to high emission levels at some plants
- There is no regulation in India for parameters like emissions of gaseous ammonia from urea manufacturing
- The emissions which contains urea dust, ammonia and oxides of nitrogen and carbon, also affects the growth and productivity of vegetation and crops around a plant
- Plants are not managing their hazardous waste properly, for which they have received notices or directions
- Ash pond maintenance has emerged as an issue at most plants
- Handling and storage of fly ash is inefficient and causes pollution
The Fertilizer sectors are growing at a very fast pace in India due to the demand of fertilizers in the agriculture sector. The above discussed concerns need to be ratified as soon as possible.
